Ethernet Network Interface Unit

Intelligent Ethernet Management Platform

Spec Sheet

For Ethernet services to fully deliver on the promise of lower costs and higher reliability, remote management of the network becomes essential—especiallyas subscriber numbers increase. Remote isolation of troubles and performance monitoring are minimum requirements for carrierclass Ethernet service.

Service providers can now create an intelligent Ethernet management platform with ADC’s Ethernet Network Interface Unit (ENIU). Installed at the remote premises, the ENIU provides the demarcation point between the customer and carrier network. By providing the ability to

sectionalize the network at the customer interface, the ENIU enables the carrier to remotely assess whether trouble conditions reside within the carrier or customer network.


Saves operations time by limiting technician dispatch for troubleshooting and turn-up.

Reduces network downtime through proactive network management

via remote access for testing and performance monitoring.

Enables quicker service restoration through single end testing of signal.

Increases network availability by accelerating network trouble repair cycle.

Easily integrates Ethernet network management into existing operations by mirroring current maintenance practices for DS1/DS3 architectures.

Standards-basedsolution allows interoperability with switches, routers and test equipment.


Supports in-bandremote signal loopback for troubleshooting and testing as

well as remote failure indications and link monitoring for checking service performance.

Features UTP (RJ45) or SFP-basedoptical connections for customer and carrier interface.

Loss of power “cut through” ensures that electrical signal integrity is maintained on RJ45 interfaces if power to the unit is lost.

Configurable to 10Mbps or 100Mbps Ethernet or Gigabit Ethernet on carrier and customer demarcation sides.

Bandwidth can be port limited in 1Mb increments.

Includes enclosed carrier-sideinterfaces with LED performance indicators on the front of the unit.

Fully compliant with IEEE 802.3ah™ First Mile standards for OAM.

Accepts –48Vdcor AC power.
